 The Motorola Oncore GT GPS PC board level receiver transmits
 autonomous(now there is a word you don't hear much) position,
 velocity, heading, satellite tracking status, and time
 information. Functions include: *8-channel receiver. *Antenna
 current sense circuit. *Operates from a regulated +5Vdc. *TTL
 interface to host equipment. *3 dimensional positioning within 25
 meters, SEP(without selective availability {SA}). *Latitude,
 longitude, height, velocity, heading, time, and satellite status
 information output either continuously(once per second) or
 polled. *Differential GPS with Motorola binary corrections. *RTCM
 SC-104 differential GPS correction input or second com port.
 *Velocity filtering. *1PPS output(+/- 500ns accuracy). Used by
 Ham Radio Operators for automatic position reporting
 system(APRS). *NMEA output:
 Message Description
 GPGGA GPS fix data
 GPGLL Geographic position-latitude/ longitude
 GPGSA GPS DOP and active satellites
 GPGSV GPS satellites in view
 GPRMC Recommended minimum specific GPS/transit data
 GPVTG Track mode good and ground speed
 GPZDA Time and date
 An exclusive "Motorola Oncore GPS QuickStart Guide" is included
 with each receiver, and is also on the Internet at
www.bgmicro.com under "Tech Docs". The guide includes a schematic for a PC
serial interface, Internet links for free and low-cost GPS software and
detailed information on the Motorola Oncore GPS receiver. IMPORTANT:
Advanced electronics experimenter skills are required to interface this
receiver to a PC or an embedded microprocessor project. Brand new.

ACS1397...........................................$14.95

Not sure how many they have or how steady their supply is, but looks good
for now. TTYL

>Well so far my cost findings on the GPS modules is around $85 + $33 for
antenna if you want to have a steady supply of the sample product for the
next year, or $50-65 ($25 for antenna) surplus for unknown amounts. (This
pricing is for the OnCOre Mototola GPS module from

>This still puts our current project at risk of never getting done as we
need a steady supply at $50 for the module and antenna!

>So the search continues for a cheaper alternative......
